HPA Replacement 
 
 
Open or loose RF connections during operation may cause electric arcs 
that can cause burns and eye injuries, as well as damage equipment.  
Always ensure that the sub-system has been placed in standby mode 
and DC power to the HPA has been switched OFF. 
 
 
The HPA may be very hot from operation.  Allow the HPA surface to cool 
before removing the equipment. 
 
 
 
Always remove/install the high power amplifiers with the aid of a second 
handler.  The high power amplifier weighs approximately 55 lbs. 
 
 
To prevent damage to the connectors, do no stand the HPA on its rear 
panel.
